To make “down” days easier to stick to, Johnson recommends opting for meal replacement shakes. They’re fortified with essential nutrients and you can sip them throughout the day rather than split into small meals. However, meal replacement shakes should only be used during the first two weeks of the diet — after that, you should start eating real food on “down” days. The next day, eat like normal. Rinse and repeat! (Note: If working out is part of your routine, you may find it harder to hit the gym on the lower calorie days. It may be smart to keep any workouts on these days on the tamer side, or save sweat sessions for your normal calorie days.)

When you eat a meal, your body spends a few hours processing that food, burning what it can from what you just consumed. Because it has all of this readily-available, easy to burn energy (thanks to the food you ate), your body will choose to use that as energy rather than the fat you have stored. This is especially true if you just consumed carbohydrates/sugar, as your body prefers to burn sugar as energy before any other source.
The purpose in fasting for God is not about giving up food; it is about removing the obstacles that get in the way of fully focusing on Him. Human beings are conditioned to eat, usually 3 meals a day and snacks. We are so focused on what we are going to eat next, we leave very little room in our minds for thinking about God. Removing the food will free up your mind so you can meditate on God.
Fasting also helps us learn the lessons of the Day of Atonement : forgiveness, reconciliation to God and the need to resist Satan and pray for the time of his removal (Revelation 20:1-3 Revelation 20:1-3 1 And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand. 2 And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years, 3 And cast him into the bottomless pit, and shut him up, and set a seal on him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.

Yes, you'll be hungry at times—but it's not necessarily overwhelming or constant. "Hunger doesn't seem to get worse as the day goes on, and some of our studies report increased fullness and satisfaction," says Kristin Hoddy, Ph.D., R.D.N., a dietitian in private practice who has researched fasting. "Some subjects remarked that they'd get distracted and 'forget' they were hungry."

I recently got in touch with Kane, a reader who’d emailed me in the past, to hear about his experience with fasting because I’ve been noticing the buzz growing louder lately. Famous enthusiasts include reality TV star Kourtney Kardashian, musician Moby, and model Molly Sims. Actor Chris Pratt has been Instagramming about his Bible-based fast.

On the other five days of the week, there's no calorie cap, and no food is off-limits.
